Don't Ignore the Issue of Blood in Stool

我們每日進食的食物會經過食道，然後入胃進行消化，再透過小腸、大腸吸收後化成大便排出體外。若然上述任何一個器官發炎、出現潰瘍、長有息肉或腫瘤，你的大便便有機會混血。

大便出血可呈顯性或隱性。顯性即指大便明顯附血，在年輕人中最常見的成因大多由長期便秘、長期谷便以致肛門口血管膨漲受壓形成痔瘡，又或肛門表層撕裂構成肛裂，兩者均於排便時同時排出鮮血。

隱性便血即肉眼無法察覺，必須透過大便隱血測試始能發現，但若十二指腸或胃嚴重潰瘍致大量出血，亦會排出黑便或混有鮮血。因隱性便血難以察覺，故若發現大便習慣改變、大便附有黏液、出現腹痛、作嘔、貧血及胃口變差等情況，請立即求診，因你有機會患上腸炎、腸息肉、潰瘍，甚至腸臟長有腫瘤。

除便血要即時求醫檢查外，年齡五十歲以上人士、家族有遺傳性腸癌者，應每五至十年照大腸鏡作防範未然。為保腸道健康，建議多菜少肉，多進食高纖食物、連皮生果和充足開水幫助腸臟蠕動易於排便。當然，由今天起習慣沖廁前要「望一望」。
